DPDK Summit, San Francisco
August 17, 2015
DPDK Summit San Francisco 2015 – August 17, 2015
The DPDK community met at the Westin St. Francis Hotel in San Francisco to discuss the application of DPDK to a variety of industry segments including telecom, cloud, enterprise, security, and financial services. The event enabled the DPDK open source community to share DPDK usage and implementation; to hear from DPDK developers, contributors, and users; and to build the DPDK community.
Opening Remarks and Kickoff to DPDK Summit
Tim O’Driscoll (Software Engineering Manager for DPDK, Intel)
On August 17, 2015, Tim O’Driscoll, an Engineering Manager from Intel, provided the opening remarks to kick off the DPDK Summit 2015.
Leveraging DPDK to Scale-Out Network Functions Without Sacrificing Networking Performance
Tim Mortsolf (CTO and Co-Founder, RIFT.io), Scott Myelle (VP Solutions Architecture, RIFT.io)
NFV application workloads are deployed in ecosystems with varying network attachment conditions that determine the availability of specific DPDK technologies. DPDK technology has rapidly evolved to support multiple I/O models ranging from dedicated access with PCI pass-through, shared access with SRIOV, and vhost-user offload using a DPDK enabled Open vSwitch. This presentation demonstrates how to write a flexible network function that can utilize DPDK to its full potential while retaining the ability to run in a non-DPDK environment.
Aspera’s FASP Protocol Uses Standard Hardware and DPDK to Achieve 80Gbps Data Transfer
Charles Shiflett (Senior Software Engineer, IBM Aspera Solutions)
Charles Shiflett will review the technologies and design approach to send data at a rate in excess of 1 TB every two minutes. Aspera Fast, Adaptive, and Secure Protocol (FASP®) is a breakthrough transfer protocol that leverages existing WAN infrastructure and commodity hardware. Code samples showing the use of DPDK, AES-NI, FASP Sockets, and direct I/O to create a zero-copy transfer technology will be discussed.
Future Enhancements to the DPDK Framework
Keith Wiles (Staff Architect, Intel)
This session will provide insight and gather community input on forward-looking activity in advancing DPDK to include connectivity to hardware accelerators and SOC support. Keith will review the need for additional devices and functionality within the DPDK framework including supporting non-PCI configuration, external memory manager and event programming model utilized by many SOCs. The session will drill down on the use of a crypto device within the DPDK framework by reviewing an early proof of concept of a software and hardware implementation of the device.
It’s Kind of Fun to Do the Impossible with DPDK
Yoshihiro Nakajima (Researcher, NTT Network Innovation Laboratories)
NTT Network Innovation Laboratories will present lessons learned from a one year experiment on SDN/OpenFlow Lagopus Switch development and trials on ShowNet SDN-IX from Interop Tokyo 2015. A co-design of FPGA NIC, DPDK library extension and software data plane is indispensable to improve packet lookup/processing performance and to reduce CPU resources for 100Gbps packet processing performance. Additionly, NTT will share a carrier use case activity on hybrid SDN with autonomous network control and network policy control by their Lagopus switch and OpenFlow technologies.
Design Considerations for a High-Performing Virtualized LTE Core Infrastructure
Arun Rajagopal (Technology Architect, NFV and Wireless Core, Sprint), Sameh Gobriel (Senior Research Scientist, Intel Labs)
Sprint’s expectation is to achieve similar performance in moving from purpose built ASIC based platforms to virtualized network solutions running on high volume servers. This session will discuss the technical challenges in achieving a scalable solution that addresses the required transaction rates and throughput of a carrier network. Learn how DPDK, VM to VM communication optimizations, and cluster scaling technologies work together to create a scalable LTE core infrastructure built on high volume servers.
Evaluation and Characterization of NFV Infrastructure Solutions on Hewlett-Packard Server Platforms
Al Sanders (Lead Developer, Hewlett-Packard)
The HP Servers NFV Infrastructure Lab was formed to evaluate DPDK based environments to ensure that HP Server Platforms can provide the best possible performance for hosting NFV Solutions. The lab has partnered with a number of NFV providers, including Intel’s Open Network Platform and 6WIND. Our testing methodology will be presented with a focus on packet processing throughput and latency in a variety of DPDK enabled configurations, including bare metal, SR-IOV, and accelerated virtual switches. Examples of results using Intel’s ONP and 6WIND technologies will be presented.
Open Discussion Panel (Q&A with Speakers)
Jim St. Leger (Software Product Line Manager, Intel Network Platforms Group)
Jim St. Leger, Intel’s Software Product Line Manager, led a discussion with DPDK experts. During this time, DPDK Summit attendees had the opportunity to ask detailed questions of the day’s presenters.
